This invention relates to valves, and more particularly to aconstruction suitable for gauge cocks, etc., operating under highpressures. Where high pressures, for instance over one thousand pounds,are involved, the requirements imposed on the valve are different andmuch more exacting than for the more customary low pressures; and itisamong the objects of the present invention to provide a constructionwhich is reliable, and which allows of ready repairs and renewals. Otherobjects and advantages will appear as the description proceeds.

To the accomplishment of the foregoing and related ends, the invention,then, consists of the features hereinafter fully described, andparticularly pointed out in the claims, the following description andthe annexed drawing setting forth in detail but one of the various formsin which the principle of the invention may be used.

In said annexed drawing:

Fig.4 1 is a central longitudinal section showing an embodiment of theinvention; Figs. 2, 3 and 4 are sections taken on planes indicated bythe lines IIII, IIIIII, and IV1'V, respectively, Fig. 1; and Fig. 5 is afragmentary side elevation.

The reference character 1 in the drawing designates a connection-memberthreaded at one end for securing into a gage column or I other part towhich it is to be applied, and

slightly recessed at the other end to receive a valve seat member 2, athin gasket being interposed at 3. The valve seat is preferably oftubular form, having a more or less well defined shoulder 4, and is heldin position by the valve-casing 5 which is flanged at 6 and engaged by aunion nut 7 threading onto the connection member. Within the bore of thevalve-casing a valve-plunger 8 is arranged for movement to and from thevalve seat. This plunger has a tapered end 9 to coact with the annularedges of the valve seat, and adjacent thereto a discharge nozzle 10 istapped into the valve-casing. The nozzle 10 preferably has its outlet 11somewhat deflected angularly so as to divert the discharge stream. Thevalve-plunger has an operating means in the form of swing levers orlever by a pin 18 set through the hub 13 across in the castellations ofthe plug 14. On the inner end of the hub 13, there are provided lugs orprojections 19 extending in the general plane of the hub, and such as tostrike against the nozzle 10 as an abutment when turned either waythrough the corresponding are left. In this manner the range of movementof the hub is limited to the arc of rotation determined by the lugs andthere is no danger of the hub being inadvertently screwed entirely offwhen in use, but when repairs or renewals are required it is a simplematter to take out the abutment 10 and then the hub member may beremoved.

The assembly and manner of use of the device will be clear from theforegoing. Movement of the lever 12 will by virtue of a screw-threadedmounting, advance or retract the hub 13 and with it the connecting-plug14 and the valve-plunger 8. Only a relatively slight excursion of motionis required, and this may be determined accordingly by the are leftbetween the lugs 19 as a path of motion rotarily. Accurate seating ofthe valve plunger may be secured by means of the adjustable plug 14, andby having the threaded connection of this into the hub on a finer pitchthan that of the threading between the hub and the valve casing 5, adesired fineness of adjustment may be had.

It will thus be seen that the device as a construction, the wear whichoccurs in the threads soon allows of lost motion and faulty seating, andconsequent leakage, and when it comes to repair,'the valve as a wholehad to be discarded. lVith the present construction however, it will beseen that the valve-plunger is entirely independent of wear directlyefiecting its engagement with the operating means and such wear as mayoccur may be readily compensated, while by arranging the operating screwthreads on a larger external diameter instead of on the relatively smallplunger, a large thread and quick action pitch is had, but at the sametime with no direct danger of the pressure in front of the valve plungeroccasionin g a release or direct blowback of the valve-plunger. Againthe valve plunger is positively actuated by means of a connection (notshown) depending from the end of each of the swing levers both inopening and in closing and there is thus no danger of the valve stickingto its seat such as commonly occurs with valves of the type notpositively actuated for opening. As a further safeguard also, it will beseen that the valve plunger is positively rotated at the same time thatit is advanced or retracted and in this manner also the danger ofsticking is further prevented, and accurate seating is insured.

Other modes of applying the principle of the invention may be employed,change being made as regards the details described, provided the meansstated in any of the following claims or the equivalent of such beemployed.
